Abstract
Two series of Dextran-graft-Polyacrylamide copolymers with Dextran backbone of different molecular masses and different numbers of PAA grafts have been synthesized and characterized. Their abilities for the stabilization or destabilization have been examined for a kaolin suspension of moderate concentration within the nephelometric method. The analyzed copolymers have been found to be stabilizers of the suspension when applied in low doses and to be flocculants when applied in moderate or high doses. The mentioned properties are dependent on both molecular mass of a copolymer, as well as on its molecular architecture.
